The cost of the book is less than a couple of tankfulls, which for me amounts to £108 - fifty four quid a fill from very low - 9.8 gal tank. Mind you, if I were filling the 2cv, which with the single downdraft Solex does 59mpg, and whose tank holds us 5½ gallons x 2 = £60 . . . well, you get my meaning I'm sure.
Prices at stingey Co-Op in Broseley £1.23 point 9p a litre yesterday.
